A purine derivative represented by the following general formula (I): (see formula I) wherein R2 is a hydrogen atom or a hydrocarbon group containing at most 14 carbon atoms; any -CH2- group in said hydrocarbon group may be replaced with a carbonyl group, a sulfonyl group, -O- or -S- when said -CH2- group is not directly attached to the purine ring or is in -CH3 group not directly attached to the purine ring; any =CH2 group may be replaced with =O or =S; C-H group in said hydrocarbon group may be replaced with N, a C-halogen group or a C-CN group when said C-H group is in -CH2- group not directly attached to the purine ring, in -CH3 group not directly attached to the purine ring, in > CH- group not directly attached to the purine ring, in =CH- group not directly attached to the purine ring or in =CH2 group; R6 is a hydroxyl group, an amino group or an amino group mono- or di-substituted with a hydrocarbon group containing at most 10 carbon atoms; R8 is a hydroxyl group, a mercapto group, an acyloxy group containing at most 18 carbon atoms or an oxycarbonyloxy group substituted with a hydrocarbon group containing at most 19 carbon atoms; R9 is a hydrocarbon group containing at most 14 carbon atoms; any -CH2- group in said R9 may be replaced with a carbonyl group, a sulfonyl group, -O- or -S- when said -CH2- group is not directly attached to the purine ring or is in -CH3 group not directly attached to the purine ring; any =CH2 group may be replaced with =O or =S; C-H group in said R9 may be replaced with N, a C-halogen group or a C-CN group when said C-H group is in -CH2- group not directly attached to the purine ring, in -CH3 group not directly attached to the purine ring, in > CH- group not directly attached to the purine ring, in =CH- group not directly attached to the purine ring, in =CH2 group or in =-CH group; or its tautomer or pharmaceutically acceptable salts thereof, and an interferon inducer, an anti-virus agent or an anti-cancer agent which comprises said purine derivative or pharmaceutically acceptable salts thereof as an active ingredient.

Cette invention se rapporte au dérivés de purine représentés par la formule générale (I), à leurs tautomères ou à des sels pharmaceutiquement acceptables de ces composés, ainsi qu'à des inducteurs de sécrétion d'interféron, à des agents antiviraux et à des médicaments anticancéreux contenant ces dérivés. Dans ladite formule (I), R<2> est hydrogène ou hydrocarbyle (où -CH2- qui n'est pas directement lié au squelette de purine et CH2 dans -CH3 qui n'est pas directement lié au squelette de purine peuvent être remplacés par un groupe carbonyle, un groupe sulfonyle, -O- ou -S-; =CH2 peut être remplacé par =O ou =S; et C-H dans -CH2 non directement lié au squelette de purine, C-H dans -CH3 non directement lié au squelette de purine, C-H dans >CH non directement lié au squelette de purine et C-H dans =CH2 peuvent être remplacés par N, C-halogéno ou C-N); R<6> est hydroxy ou amino éventuellement substitué par un ou deux groupes hydrocarbure; R<8> est hydroxy, mercapto, acyloxy ou oxycarbonyle substitué par un hydrocarbyle; et R<9> est hydrocarbyle (où -CH2- non directement lié au squelette de purine et CH2 dans -CH3 non directement lié au squelette de purine peuvent être remplacés par un groupe carbonyle, un groupe sulfonyle, -O- ou -S-; =CH2 peut être remplacé par =O ou =S; et C-H dans -CH2 non directement lié au squelette de purine, C-H dans -CH3 non directement lié au squelette de purine, C-H dans >CH non directement lié au squelette de purine, C-H dans =CH- non directement lié au squelette de purine, C-H dans =CH2 et C-H dans CH peuvent être remplacés par N, C-halogéno ou C-CN.
